Individual marking method applied in echinoderm breeding process achieved through BLUP method

Abstract

The invention provides an individual marking method. According to the method, the problem that in traditional breeding, echinoderms are difficult to mark is solved, individual marking can be conveniently performed on the echinoderms such as sea cucumbers and sea urchins, the characters such as individual feed coefficients which cannot be recorded through traditional fluorescent marking can be also recorded besides that the individual growth characters can be monitored, and compared with traditional fluorescent marking, the method has the advantages that the cost is lower, and selected individuals can be more easily identified in young echinoderm selecting. Due to the method, the possibility of breeding the echinoderms through the BLUP method is achieved. Accordingly, the method has multiple advantages and is particularly suitable for being applied and popularized in the breeding field and very wide in market prospect.

Description

technical field [0001] The invention relates to a marking method, in particular to an individual marking method in the echinoderm BLUP breeding process. Background technique [0002] BLUP, or Best Linear Unbiased Prediction, is the most widely used individual breeding value estimation method in animal and plant selective breeding. It can significantly improve the accuracy of individual breeding value estimation, thereby significantly improving genetic progress. Since the 1970s, the BLUP method has been widely used in the selective breeding of livestock and poultry animals, and has become a routine method in the selective breeding of livestock and poultry animals in recent years. Although the research on selective breeding of aquatic animals was carried out relatively late, in the past two decades, the BLUP method has been used in aquatic animals such as Atlantic salmon, tilapia and other bony fishes, as well as crustaceans such as Penaeus vannamei and Penaeus monodon. groun...

AI Technical Summary

Problems solved by technology

However, for species such as sea cucumbers and sea urchins, the BLUP method is difficult to apply to breeding practice, because sea cucumbers, sea urchins and other species cannot achieve easy-to-read individual markers (fluorescent markers, etc.) that are implemented on species such as bony fishes and crustaceans. This makes the estimated breeding value unable to be used as the selection basis for the selection operation
